I have created an app on developer portal which i used to signup with facebook on my react app. Everything works fine while the app was on development mode. But after I switch to live mode, public user can't login with facebook. Only users which are added on developer role can login. The description of my app is as follows: app type: Business Business verification is done. privacy policy URL and terms of use URLs are set. App is on live mode.
Because it requires app review, try the docs first please.
